To all whom it may concern.

Be it known that l, WILL/ino B. FEATHER- s'ronn, a citizen of the United States, residing at Washington, 'in the District ot Columbia, have invented a new and useful Motion-Picture Film, of which the *following is a specification.

illy invention relates to the art of recording and reproducing objects and scenes through rapidly successive photographic images, and has for its object the projection of a tlickerless picturein natural colors. The lms herein described are those described in my previousapplication tiled d an. 23rd, 19.07, Serial Number 353,635 oi which this application is a division.

'll/ ly invention consists in a lilm for the production of motion-pictures,. which iilrn has a plurality of series oi consecutive images divided into successive groups, each series of images being differently translucent for the purpose of reproducing hues similar to those of an original subject or scene, the translucency varying in place and degree to correspond with the intensity and distribution ci a certain color in an origifurther consists, broadly, in a lrn having a number orn photographic positive images, so arranged, that when projected, the projection oi 4one image Will overlap or dissolve into the projection ot another image.

ln the accompanying drawing, Figure l shovvs a nlm with three series of images for use with a machine having the lenses stepped as indicated by dotted lines. lT ig. 2 shows the saine iilm as used with intermittent leed machines, the lenses of the machine being indicated by dotted lines. Fig. 3 shows a three-series lilin in which the images are stepped Fig. l shows a single strip tilin having three series of images..

Similar reference characters reiger to like parts throughout the several views.

Pllhe rllrn described in this application and shown in Fig. 3, may be produced by and used in connection with the apparatus described and shown in my former application above referred to. ln making the exposures or projecting the views, the iilm inoves continuously, vvhile the optical parts reciprocate alternately, lirst moving regularly with Serial lilo. 376,855.

the'ilrn and' then quickly returning to a position opposite the succeeding portion' of the lilm. The return of. a given lens is' made While the view through the lens is occulted, the other lenses being exposed. Positives may be made on similar strips of films by contact in the usual manner. ll or colored reproduction, the exposures are made through color filters, the projections being similarly colored by color iilters, or the iilrn itself may be stained or dyed, each series dinerently.

rlhe shading of the severalviews indicates in general the color of the filter through `which a series of: negatives would be .taken looking to normal color edects in reproduction, and also the color of the lter or the stain used with the positives in projection.

ln Figs. l, 2 and 3, A, A1, A, represent negative lilins. Series G, G1, and G2, were taken through a'green i'ilter, series R, R1, and R2, through a red lilter, and series B, B1, and B2, through a blue filter.

ln Fig. ll, the images l, Il, 7, l0, and i3 constituting a portion of one series, have been inodii'ied by a green iilter, and images 2, 5, 8 and ll, etc.,'have been modilied by a lter.

The object of my new method is not only the analysis and synthesis of motion by rneans of pictures, but also the colored and lifelike reproduction of objects in which motion may or may not be an important feature. lin fact, perfectly tliclrerless projections in colors offer a comparatively sirnple solution of the problem of color photography Whether et stationary or moving objects. The-flicker is avoided by projecting an image of one series of positives upon the viewing screen before the preceding image (of another series) has been occu ted. The dissolving isso perfect as to be unnoticeable Steadiness of the view is further assured by the eXtra Width of the ilrn and its slow and continuous motion.

ln practice it will be found convenient to stain the positive lrn, say red, green and blue, (Fig. 3), instead ofvprojecting the black and White irna ges 'through color iilters, it being obvious that similar. blended hues Will result. A complete picture is inferred to be in natural colors, hence each mono image which was photographed by light of a single primary color. A primary color l is held to be some sliade ot red, green, or

V"blue-violet, suiiiciently pure for-practical reproductions, but not necessarily correct spectroscopically, nor is my invention limited to the exact styles of ilni shown and cleyscribed, its principal object being to do raway with separate color filters and the cornplications which they involve, thus removing the einer diiiiculty in the projection or? naturally colored pictures.

claim:

l. A motion picture lm having plural series of images representing successive aspects oi an object or scene, a portion or" the images `naving color values ierent from those of another portion, each portion loeing colored uniformly to correspond with its color values.

2. A motion picture lni having plural se- 4ries of picture factors, collectively representing successive aspects of an object or scene, each series having oli'erent color values to correspond with a different pri.- rnary color, and uniformly stainecl with that einer,

ineens@ S. A film provisie@ with images repre- Santingv successive aspects or an object or scene, images being divided into plural series, each or which represents di'iiiere'nt color values, anrl is diierentiy and uni.- tormly stained, the color values and color stain oi each series corresponding with one or@ the primary colors.

4. Plural series of picture factors collectively representing successive aspects oi3 an object or scene, each factor being uniifornily colorecl and having color values to correspend with one of the primary color sensations, eacii series having an equal number of factors, and all the factors inany one series leaving substantially the saine color and; color values.

5. .l motion picture 'iin divided into image areas differentlyanrl uniformly colorecl in groups of two or more to correspon@ with the primary color sensations, each area comprising a picture actor having Acolor values corresponding Witli its color.

6. A motion picture iin having plural series 'picture factors, each series being translucent to one primary color only, and having corresponding color values.
